To all whom it may concer/n.' Y

Be it known that I, .Ivon Gorrrmnn ALEXANDER DU Rims, a citizen of the United Sta-tes, residing at W innetka, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cross-Chain Connecters for Antiskid Chains, of which the following is a specification.

This inventionrelates to improvements in connecters particularly adapted, though not necessarily limited in .itsusevfor connecting the cross chainsof an anti-skid chain with the side links of such devices, and one of the objects of the invention is to provide an improved, simpleand efficient device of this character by means of the use ofwhichthe cross' chainsmay be readily. secured in position and as readily removed or, disconnected from the side chain linksr when desired.

A further object istoprovide an improved device. of this character which may be permanently connected with the side Vchainlinks and to which device the Icross chains maybe attached and disconnected therefrom, thereby insuring that 4when new cross chains are applied, they. .will be uniformly nspaced throughout the length of the side members of the antirskid chain. c

i A further obje-ct istoprovide an improved 30 device of ythis character which may be readily manipulated without the use of tools, and so constructed that ,the stress of the side chains or members as well as the stress of the crossr chains. will assist in maintaining the parts in locked relation, n

.To the attainment of these ends-and the accomplishment of other new and useful objects ,as will appear, the invention consists in theA features of novelty in substantially the construction, combination andarrangement of the several parts hereinafter more fully described and claimed and shown in they accompanying drawing illustrating this invention, and in which-- Figure 1 is a view in elevation showing a device of this. character constructed in accordance with the principles of this inven tion as employed in connecting a cross chain to one of the side members of an anti-skid chain.

Figure 2 is an enlarged detail perspective view of the connecting device.

Referring more particularly to the drawing the connecting device consists essentially of two members and 11 pivotally connected intermediate ltheir ends as at 1-2 so asv to cross each other; The extremity lof the member 10 and the yextremity 1li ofthe member 11v are; shaped -tor Vform opposing hook shaped portions which are adapted to overlap each other. The faces 15 of the yhook shaped extremity 13, andV 16 of the hook shaped extremity 14 are inclinedfor a rpurpose to be hereinafterset forth. Formed at the other extremityof-the member 10 is jan eye 17 and formed at the other extremity ofthe member 11v is an eye 18.` These eyes are adapted to engage the wall-19 of an elongated link 20. The link 20, any number of whichfmay' be provided, constitutes a. portionof the side member 21 of an? anti-skid chain. By the provision ofthe eyes 17-,18 on thefends of the members 10 and 11 it will `be manifest that the members maybe rocked about their pivot; l2 4so asto separate the hooked extremities or# ,causey them tobe moved towards each other. VYVhefnthe eyes '17 and 18 are moved toward'sveac'h other the hooked extremities will begopened but when the eyes .are separated the hooked extremities willbe closed. .y Y Y y y Inuse, the` opposed hook shaped extremities 13 and 14.; areladapted to engage lin a link 22 of thev cross chain 23, and 'from opposite sides. of the link and Awhenin position the stress: of; the .side mer'nbersl 21- andl link 20 together with the cross chains 23upon the connecting device will operate, by reason. of they inclined ,surfaces 15 and 16 to draw'the hookedV shapedA portions towards each other and rmly lock or secure the cross chain in position. f

1 In the event that itis desired to remove the crosschain all that is necessary, is to move the eyes 17418 towards each other and the hook shaped portions will be separated. If desired and as a means for assisting in holding the members 10 and 11 in locked relation with respect to each other, an elastic element 24 such as acoil spring or the like mayubeprovided and encompasses the side member 19 of the link 20. This elastic member 24 may preferably be in the form of a coil spring and is disposed between the extremities of the members 10 and 11, which carry the eyes 17 and 18. When it is desired to detach the cross chain 23 the members 10 and 11 are rocked about their pivots against the vstress of the elastic element 24. Y

Obviously any number of these connecting devices may be employed, and when employed in the manner as shown in the drawing they will constitute a permanent portion of the side members so as to insure that the cross chains will be properly spaced throughout the lengths of the side members when the cross chains are in position.

While the preferred form of the invention has been herein shown and described it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.

That is claimed as new is 1. A device of the character described including co-operating members pivotally connected intermediate their ends, one extremity of the members being shaped to form opposed hook shaped portions adapted to engage in a link of a cross chain and from opposite sides of the link, an elongated link,y means loosely connectingV the other ends of said members with the said elongated side link for free movement towards and away from each other to open and close the'said hook shaped extremities, and means independent of and remote from the pivot of the membersA and tending normally to separate theends Vofthe 'said members which are connected with 'the saidr elongated side link to close the said hookshaped ends with respect to each other. Y

2. A device of the character described in cluding co-operatinglmembers connected intermediate their ends for relative movement towards and awayfrom each other, one eX- tremity of the members being shaped to form opposed hook 'shaped portions adapted to engage in a link of across chain and from opposite sides of thelink, an elongated link, means loosely connecting the other ends of said memberswith the said elongated side link for free movement towards and away from each other to open and close the said hook shaped extremities, and a resilient element carried by one wall of the elongated side link and disposedbetween'the ends of the said member that are connected with the last said link and tending normally to separate them. p 4 y 3. A device of the character described` including co-operating members connected intermediate their ends for relative movement towards and away from each other, one eX- tremity of the members being shaped to form opposed hook shaped portionsadapted to engage in a link of a cross chain and from opposite sides of the link, the faces of the hook shaped portions which engage the said link-being inclined whereby the stress of the link upon said faces4 will tend to draw the hook shaped portions towards.

each other, an elongated side link, means loosely connecting the other ends of the said members with one wall of the said elongated link for movement towards and away from each other, and a resilientpelement encompassing the wall of said link intermediv ate the ends of the said members that are connected with the side link and tending normally to separate suchv ends of the members. v

4. A device of the character described includingy cross membersA pivotally connected intermediate their ends, one end of said members being shaped to form opposed hooks adapted to engage in a link of a cross chain and from opposite Vsides of the link, an elongated side link, eyes formed at the other ends of said members and through which eyes one, wall of the said side link loosely passes, the saideyes being freely movable towards and away fromeach other to open and close the said hook shaped ends, *A

hooks adapted to engage in a linkof across chain and from opposite sides of the link, an elongated side link, eyes formed at the other ends `of said members and through which eyes one wall of the'lsaid Yside link loosely passes, the said eyes being freely movable towards and away from each `other to open and close the said'vh'ook shaped ends, and a resilient element encompassing the wall of the said side Ylink intermediate said eyes and tending normally to separate the latter.
